Answer:
5
Step-by-step explanation:
Convert the element to fraction:
/
Switch the division to multipl:
2/1 * 2/5
Cross multiply:
2 is elimiated and 1 and 5 remain.
Answer is 1/5 which is 5.
Answer:
Coordinates of midpoint are (8,1.5).
Step-by-step explanation:
Given coordinates of end points are;
(7,4) and (9,-1)
we can find the coordinates of mid-point,
Here,
x1 = 7 and y1 = 4
x2 = 9 and y2 = -1
Putting these values in formula
Coordinates of mid point =
Midpoint =
Midpoint =
Midpoint = 8 , 1.5
Hence,
Coordinates of midpoint are (8,1.5).
If f(4a) = 80, then the value of "a" is 4.2
<em><u>Solution:</u></em>
Given that cost for the olive oil used to fill the containers on the tables in an Italian restaurant is given by the function:
f(x) = 5x – 4
where "x" represents the number of quarts of olive oil
f(x) represents the quarts of oil used
To find: value of "a" when f(4a) = 80
Substitute x = 4a in given function
f(4a) = 5(4a) - 4
80 = 20a - 4
20a = 84
10a = 42
a = 4.2
Thus the value of "a" is 4.2
